[parisc-linux] Basic HPMC handler submitted.

[Frank Rowand]

I have submitted a basic HPMC handler.  If an HPMC occurs, the message:

  >>  HPMC occurred  --  resetting system  <<

will be printed and the machine will be reset (except for the A180, which
wedges in the PDC call that is supposed to reset the system - power cycle
your A180).

Feel free to critique the code or fill in the gaps that I left...

The files modified are:
